This commit implements the necessary code generation logic for Rust structs annotated with #[repr(transparent)]. This attribute allows a struct with a single field to have the same memory representation as that field, enabling seamless interoperability with C-compatible types. The changes cover compilation of field access and struct construction for these types.
